Could you, please, explain me what Charcoal lighting fuel is ?

About the MDF, from my personal experience, I can confirm it
produces a very dangerous dust.
Well, the dust itself (being so thin) represents a serious hazard
for the lungs.
Then the chemical components of the glue/resins contained in the MDF
also represent a serious treath to your health.

Several years ago I used MDF for a prototype and to obtain the
desidered roundness of the edges I had to machine the panels
producing a lot of thin and light dust.
Despite I was wearing a good breathing mask, the dust suspended in
the air affected my breathing ways and I suddenly became allergic to
the MDF and to most of wood dusts.
My allergy was so strong that I coundln't even get close to the door
of a wood-workshop. And it lasted for years.
Now I'm free, but for more than six months I couldn't breath with my
nose, sometimes waking up breathless in the middle of the night.

Not a nice experience.

Take care and keep safe using those materials, a good venting and
vacuuming system are not a luxury ad-on but a must.

Paolo:

Charcoal lighter fluid is just a fluid, usually made from kerosene but not
always, that is used to soak charcoal in a grill for cooking. After you soak
the charcoal in the lighter fluid, you light it and then the fluid burns away
leaving the charcoal burning for cooking. Mineral spirits or kerosene
should work as well as the lighter fluid, however, you can purchase ( here in the
U.S.A.) charcoal lighter fluid that doesn't have any odor to it and I think
that is what has attracted several on the list to use it. Also, it is pretty
cheap.

Regarding MDF, you are totally correct. If you are going to cut wood
products of any type, a dust extraction system is a requirement not a luxury. I
was the senior engineer here in the U.S.A. for a company called SCMI it is the
U.S. division of SCM Spa headquartered there in Rimini, Italy. I worked for
them for around 15 years and was a contract consultant for another 4+ years
after going out on my own. When I was with them, I learned just how toxic
wood dust can be. I ended up almost destroying my vocal chords because I didn't
know that when I first went to work for them and in that industry. It took
months of care and I was not even allowed to speak for weeks until they were
finally healed. After that, I wear a GOOD dust mask when I go into factories
to repair or install machinery.
